Definitions

  • the present invention relates to electric socket connectors.
  • the invention relates to electrical connectors of the kind in which electrical connection with an associated plug contact is effected by means of a pair of opposed spring contacts bearing on opposite sides of said plug contact.
  • multiway connectors typically comprise associated plug and socket connectors each having a plurality of so-called male and female contacts respectively inserted into appropriately shaped injection mouldings of electrically insulating material.
  • Each female contact may comprise one or more cantilever springs of sufficient rate to provide an adequate force at the points of electrical contact with the associated male contact.
  • the female contacts may be required to provide, often with the same cantilever springs, sufficient retention forces to keep the plug and socket connectors in proper engagement.
  • an electric socket connector in which an electrical connection between a contact of said socket connector and a contact of an associated plug connector is effected by means of a resilient portion of said socket connector contact which is arranged to bear on said plug connector contact, there is provided on said socket connector contact at least one other resilient portion which is arranged to bear upon a surface of said plug connector contact at a point other than that or those in which said electrical connection is effected when said plug and socket connectors are fully engaged.
  • each socket contact comprising a pair of opposed resilient members arranged to bear on opposite sides of the respective plug contact when the socket and plug connectors are fully engaged, there is provided on each socket contact at least one other resilient member which is arranged to bear upon the surface of the respective plug contact in an area other than those in which said electrical connection is effected when said socket and plug connectors are fully engaged.
  • the resilient member may be arranged to bear on a surface of said plug contact substantially perpendicular to said opposite sides of the plug contact.
  • each female or socket connector contact 1 is cut and formed from thin sheet metal, such as phosphor bronze, the cut shape shown in Figure 1 being bent at right angles along the dotted lines 2 to form two opposed cantilever springs 3 with a third cantilever spring 4 lying alongside and generally in a plane at right angles to the general planes of the springs 3.
  • the springs 3 and 4 are curved adjacent their free ends to facilitate engagement with an associated substantially square-section plug contact 5 and to define respective contact areas which are arranged to bear upon that contact 5.
  • the springs 3 are formed to exert comparatively low forces on the contact 5 sufficient to provide effective electrical connection, while the spring 4 is shorter and stiffer to provide the higher force necessary to keep the contacts in engagement.
  • the contacts and 5 will in use be retained within respective socket and plug mouldings 6 and 7 which will determine which faces of the contact 5 are utilised primarily for electrical contact and which are primarily for retaining purposes. It will further be appreciated that the roles of the springs 3 and 4 may be reversed, with the springs 3 made stiffer to contribute the retaining forces and the spring 4 providing the light pressure electrical connection. Alternatively the contact 1 may be shaped so as to provide two springs 4 as well as two springs 3, these springs bearing in pairs on respective opposite faces of the contact 5..
  • the areas of the contacts 1 and 5 that are directly involved in effecting electrical connections may be plated with precious metal such as gold to ensure good and reliable connection with low contact pressure.
  • the plating may be restricted to those areas of the contacts directly involved in making electrical connection.
